As one of the Eleven Fatui Harbingers, Arlecchino greatly respects the Tsaritsa, though she states that she is willing to betray the Tsaritsa if their interests ever were to differ. Arlecchino is working to achieve her goals by acquiring the Gnoses on her behalf. She handles Fatui matters with utmost importance and comes off as graceful and cordial. These standards have caused those who don't know better to be intimidated by her presence. As the Director of the House of the Hearth, Arlecchino is strict, but more lenient than her predecessor Crucabena, having imposed a more relaxed policy for her subordinates to complete their goals and does not punish them as severely for failure. She appears to have a soft spot for children, seeing that many members of the House of the Hearth are young and orphaned children taken in across Teyvat and views them all as her "children," becoming particularly angered when their well-being is threatened or manipulated. While she does not like betrayal, she is not as cruel, as she was willing to spare traitors who demonstrated sufficient willpower by "executing" their identity in the House via excruciating mind-wipe rather than outright killing them physically; it is unknown what happens if someone is unable to withstand the pain this process causes, nor is it known how Arlecchino disposed of traitors before she implemented this "solution." Arlecchino is disliked by her fellow Harbingers, who believe her to be violent and crazed beneath her stoic exterior. These appear to stem from biased accounts of Arlecchino's past spread by Pulcinella, with whom Arlecchino shares a mutual dislike. Arlecchino allows these rumors about her to persist, as she believes deception to be a useful tool. She has pale skin, obsidian eyes with glowing red 'X' markings, black mascara on her eyelashes, and silver eight-pointed star earrings. Arlecchino has white hair with black tips, with the right side being longer than the left. Her hair is then styled into a low ponytail with asymmetrical bangs that loosely resemble a single wing that goes down her back. Her ponytail has a red strand of hair in it. Her hair clip also bears the image of a single wing. Arlecchino has blackened hands with crimson nail polish on her sharpened nails.
